Carbon seals, the traditional sealing method in process steam turbines, are weak and brittle and wear quickly – causing them to become ineffective within a short period of time. Enhance the performance of your process steam turbines by protecting the carbon rings with the Sentinel FBS from Inpro/Seal®.

The Sentinel FBS is comprised of densely packed and flexible metallic brushes that provide an extra layer of protection to slow down the natural wear of downstream carbon rings. The brush serves as the primary shaft seal while a carbon element provides face sealing in the turbine’s casing. A drop-in replacement for a standard carbon ring, the Sentinel FBS increases the mean time between repair (MTBR) to more than three times that with carbon seals.
